|The Canary Murder Case (1929) [Margaret 'The Canary' Odell]: Reportedly strangled with her own necklace. According to the tipster who sent me this information, the actual film did not show her body afterwards, although they did show it in a publicity photo (which the tipster kindly provided). (I haven't seen this movie myself.) (Thanks to Anonymous)

Prix de beaute (Beauty Prize; Miss Europe) (1930) [Lucienne Garnier]: Reportedly shot by Georges Charlia. (I haven't seen this movie myself.) (Thanks to Golgo13)
